Question: What warbird do I describe?
Clues:
1. Perhaps the most amazing fact about this warbird is the annual production number was only a few numbers greater than the number of countries utilizing it.
2. It is noted for two significant “firsts”.
3. It was a very advanced aircraft for its time.
4. In fact, only one other manufacturer was producing aircraft which could even be called “comparable” as relates to their modernish design.
5. Various models utilized various engines, from various manufacturers.
6. Both inline and radial engines were used.
7. It was in production for more than ten years.
8. It was in regular use for more than twenty years.
9. It was utilized as a passenger plane, a bomber and as a transport.
10. However, it was first introduced as a transport plane; one which could easily be utilized as a passenger plane.
11. One of the reasons for its popularity was the ease with which alternate landing gear could be fitted.
12. It was a low wing monoplane.
13. It was a cantilever monoplane.
14. Without any supporting wires or external bracing.
15. At a time when such designs were very unusual.

17. Most designs even then were externally braced biplanes with fabric covering.
18. Did I mention this aircraft was of all metal construction?

The Junkers F.13 (also known as the F 13) was the world's first all-metal transport aircraft, developed in Germany at the end of World War I. It was an advanced cantilever-wing monoplane, with enclosed accommodation for four passengers. Over 300 were sold. It was in production for thirteen years and in commercial service for almost twenty.

The F.13 was a very advanced aircraft when built, an aerodynamically clean all-metal low-wing cantilever (without external bracing) monoplane. Even later in the 1920s, it and other Junkers types were unusual as unbraced monoplanes in a biplane age, with only Fokker's designs of comparable modernity. It was the world's first all-metal passenger aircraft and Junkers' first commercial aircraft.

The designation letter F stood for Flugzeug, aircraft; it was the first Junkers aeroplane to use this system. Earlier Junkers notation labelled it J 13. Russian-built aircraft used the designation Ju 13.

Like all Junkers duralumin-structured designs, from the 1918 J 7 to the 1932 Ju 46, (some 35 models), it used an aluminium alloy (duralumin) structure entirely covered with Junkers' characteristic corrugated and stressed duralumin skin. Internally, the wing was built up on nine circular cross-section duralumin spars with transverse bracing. All control surfaces were horn balanced.

Behind the single engine was a semi-enclosed cockpit for the crew, roofed but without side glazing. There was an enclosed and heated cabin for four passengers with windows and doors in the fuselage sides. Passenger seats were fitted with seat belts, unusual for the time. The F.13 used a fixed conventional split landing gear with a rear skid, though some variants landed on floats or on skis.

The F 13 first flew on 25 June 1919, powered by a 127 kW (170 hp) Mercedes D IIIa inline upright water-cooled engine. The first production machines had a wing of greater span and area and had the more powerful 140 kW (185 hp) BMW IIIa upright inline water-cooled motor.

Many variants were built using Mercedes, BMW and Junkers liquid-cooled inline engines, see Variants below and by Armstrong Siddeley Puma, Gnome-Rhτne Jupiter and Pratt & Whitney Hornet radial engines. The variants were mostly distinguished by a two letter code, the first letter signifying the airframe and the second the engine. Junkers L5-engined variants all had the second letter -e, so type -fe was the long fuselage -f airframe with a L5 engine.

[h=2]Operational history[/h]
F 13 fy D-190 of Lloyd Ostflug then Junkers Luftverkehrs AG.

Any manufacturer of civil aircraft immediately after World War I was faced with competition from the very large numbers of surplus warplanes that might be cheaply converted - for example, the DH.9C. German manufacturers had further problems with the restrictions imposed by the Inter-Allied Aeronautical Commission of Control, which banned the production of warplanes and of any aircraft in the period of 1921-2. Junkers picked up orders abroad in 1919 in Austria, Poland and the USA and, in the following years with SCADTA (Colombia) and the United States Post Office Department. John Larsen Aircraft in the USA purchased a production licence, their machines being designated JL-6. In 1922 there were sales in England, France Italy and Japan.

In Bolivia, LAB's first airplane was a Junkers F-13; first flight took off from Cochabamba on September 23, 1925.

Junkers set up its own airline - Junkers Luftverkehr AG in 1921 - to encourage the acquisition of the F.13 by German airlines which was flying 60 of them by 1923. They also established a branch of this airline in Iran. Other marketing techniques were used, providing F.13s on cheap leases and free loans, with such effect that some 16 operators across Europe were flying them. When Junkers Luftverkehr merged into Luft Hansa in 1926, 9.5 million miles had been flown by them. Luft Hansa itself bought 55 aircraft and in 1928 were using them on 43 domestic routes. Even in 1937, their F.13s were flying over 50 flights per week on four routes. They were finally withdrawn in 1938.


Most of the F.13s produced before completion of the marque in 1932 were built at Junkers German base at Dessau. During the difficult 1921-3 period production was transferred to Junkers plants at Danzig and Reval. In 1922-3, Hugo Junkers signed a contract with the Soviet Union to produce the aircraft in a Soviet factory at Fili near Moscow which became known as "Plant no. 22". Some of these aircraft served Soviet airlines and some the Red Army.

There were some other military users. The Colombian Air Force used the F.13 (and the related W.33, W.34 and K.43) as bombers in the Colombia-Peru War in 1932-3. The Republic of China flew F.13s converted into scout bombers until the January 28 Incident in 1932, when they were destroyed by the Japanese along with the Shanghai Aircraft Factory. The Turkish Flying Forces flew a few.

A feature that made the F.13 popular internationally was the ease with which its landing gear could be converted to floats. During the formative years of commercial aviation, bodies of water such as rivers, lakes, seas and oceans were more abundant than landing strips and civil airports in many parts of the world, so seaplanes were commonplace and even, in some places, more useful than regular aircraft. Aside from the obvious addition of floats, little modification was needed for this conversion; however, the different configuration could cause issues with directional control, and so some models had their rudder extended to compensate for this.

From their introduction in 1919, commercial F.13s were in service for more than thirty years; the last commercial F.13 was retired in Brazil in 1951.

Going back to the Boeing 247. It was Boeing's version of the DC-3 that was the stimulus for Douglas designing the DC-3

Not the Boeing 247, though it does fit the clues so far. But not today's.

3. Under 1000 produced.

4. Similar in appearance to a much-better-known and somewhat larger plane manufactured by a different company.

5. The better-known plane referred to in Clue no. 4 was widely used in peacetime and flown by civilians, both before and after the war in which it served. But the plane whose name I'm looking for was flown only by the military (apart from test flights and perhaps deliveries).

That's the plane, more commonly referred to as the "Jeep." Designed to handle like a bomber, so it was difficult to fly and therefore not sold to civilians after the war. Wikipedia article with picture here: Not a bad looking plane.

Guess I have to come up with another one. I'm going to go with a "Daily Double" requiring two aircraft be identified in this one:
1) One was developed by a well known manufacturer, the other was by a relative "upstart"
Good Luck

No takers? Time for another clue:
1) One was developed by a well known manufacturer, the other was by a relative "upstart"
2) Both of these planes evolved into aircraft that be came legends a few years later

He's not looking for famous planes; rather planes which developed into famous planes. I was thinking the Mustang Mark I and the Republic P-43 Lancer. Thanks; Ernie P.

You hit it head on with the first sentence, Ernie. Unfortunately, you were a bit off the mark with the Mustang Mark I. There were three versions that could be referred to as MK I, the original P-51, the P-51A and the A-36. The only difference between the three was the armament package they carried and, with the A-36, it also had dive brakes in the wings. The B and C, making the MK II, only changed the engine to the Merlin which increased the altitude rating of the plane, as well as the top speed. The D, H and K only changed the plane by going to a bubble canopy as compared to the razor back, being designated the MK III by the British. Other than the engine change and the bubble canopy the plane didn't change so it doesn't really fit.
Now, time for another clue:
1) One was developed by a well known manufacturer, the other was by a relative "upstart"
2) Both of these planes evolved into aircraft that be came legends a few years later
3) Neither plane was considered a true dogfighter in it's original form or after it evolved
Good Luck

I'm going to stick with one of my answers and change the other. Not a dogfighter? How about the Republic P-43 Lancer,which became the P-47; and the Lockheed Model 22, which became the XP-38/YP-38and evolved into the P-38? Thanks; Ernie P.

3) Neither plane was considered a true dogfighter in it's original form or after it evolved
4) While one plane stayed close to it's original form, the other ended up with a similar wing and tail section in a slimmer design than it originally had

3) Neither plane was considered a true dogfighter in it's original form or after it evolved

5) While both of the final versions of the planes were combat veterans, only one of the original designs saw real combat
Just for a clarification, both the original planes were designed, built, accepted and put into service by their country's military
Good Luck

Just a heads up.
I'll be away from my normal internet access points for a few days so if you don't see me, that's why.
